Be it known that I, GEORGE H; Brno, a citizen of'the UnitedStates, and aresident of Brooklyn in the county of Kings and State of New York, haveinvented new and useful Improvements inv Spools, of which the followingis a specification.

This invention relates to spools for receiving ribbonand other narrowfabric-s as it is usual to prepare them for sale, and more particularlyto such spools including abody upon which the ribbon is wound andseparate end flangessecured to opposite ends of said body to retain theribbon thereon.

One object. of the invention is to provide a spool of the characterdescribed embodying novel and'improved features of construction forsecuring said end flanges to ,the body;

Other of'this character a novel and improved combination of a metal tubeand means tocooperate with said tube for obtaining a strong, durable andeasily produced assembly of the bodyand the end flanges of the spool; tothus provide in such a spool a body having an axial" opening to looselyreceive said metal tube, and flanged bushings or thimbles to fit theends of said tube and interposed between the tube and said bodyandsaidend flanges, the ends of the tube being upset or expanded to clampagainst said end flanges on said body and to obtain other results andadvantages as may be'brought out by the following description.

Referring to the accompanying drawings,

, in which the same reference characters designate corresponding andlike parts throughout the several v ews, 4 r

Figure 1 1sja longitudinal vertical sectional view through a spoolembodying the objects are to provide in a spool Figure 8 is a detachedperspective view of a modified form ofrivet tube, and

Figure 9 is a fragmentary endview of a spool including a tubularrivetQsuch as shown inFigure 8. V

- Specifically describing the embodiment of the lnvention shownoinFigures 1 and 2, the reference character-1 designates a "drum formed ofany suitable material such/as cardboard and upon which is adapted to bewound the ribbon or the like, said drum having alined axial openings 2in theends thereof. End flanges 3 of any suitable material such ascardboard; are applied to opposite'ends of the drum 1, said flangesbeing of greater diameter'than the drum 1 so as to retain the ribbonupon the drum. flanges 3 are formed with axial openings 1- to -registerwith the opening 2 in the ends of the druin l. For securing the flanges3 to the ends ofthe drum, I. utilize a metal tube 5 to loosely. passthrough the openings The 4t and 2 in the flanges and drum respectively.

upon each end of the tube 5 is fitted a thimble or flanged bushing 6 thebody of which projects into the openings 2 and 4 and the flange 7ofwhich bears against the outer surface of the corresponding end flange3, the end of they body having the flange being flared or rounded asat'50. The ends of the'tube'l') are nicked or expandedoutwardlyasindicated "at 8, into-the flared portion 50 and,. againstthe flange? ofthe corresponding thiinble- 6,. \Vith this construction, the flanges '3are firmly clamped against the ends of the-drum 1.between the drum andthe" flanges 7 of the thimbles' 6, and the upset ends 8 of the tube 5hold the *thimbles in-tight engagement with the end flanges f 'thespool. The ends of the .tube

'5 are disposed inwardly of the planes ofthe flanges'7 sons to'perinit'the spools to be closely packed end to end. The tube 5 isthus'substantially a metal tubular-rivet, and the thimbles 6 reenforce'the ends of the tube during the expandingoperation, prevent injury tothe flanges 8-a11d the drum 1 and *provide an extended-bearing on theflanges 3 around "the openings/t which prevents v tearing of the flangesfrom the thimbles and reenforces th'espool at its axis.

I In some instances, the pastebo'ard of which the drum 1 and flange '3may be formedis 's'o' fle xible as to bend inwardly or collapse a's' theends "of the tube 5 are :upset,

and accordingly I may utilize a metalsleeve 9 upon which the drum leismounted and which in turn receives the thimbles 6i and the tube 5, asshown in Figure 3 of the draw; ings. The sleeve 9 is preferably of'a'length to project beyond the ends of=tlie druniil a distance slightlyless than the thickness the end'fianges 3 of thespool, and accord inglywhenthe ends of the tube.5,,are upset, the ends of the sleeve 9ie'enforc'e" the struc ture. so; as to prevent ,.collapsi ng of,tl1eends more, theJsleeyeQ reenforcedthe spool at its center. y

A'snnilar effect, may be accomplished by the; use of ahwoodencorefor.bushing, 10 as shown in Figure 5: of" the drawings. This wooden coremaybe ofa length only suf i cient to passithroughthe, axial openin 1n M v ica-pm the drum? 1'; andsthe th nibles. (i clamp; the

Theend flanges 3 of. the spool areclan ped between the-flanges '7 of theth-imbles and the ends of thegbody 1-1. Thebody 11 may have the, ribbondirectly, woundjthereon, or

a drum having the ribbon woundthereon may be, fitted-upon the body 11in;a manner simila r;to "that illujsttated ;in Figure 5;
